Steel sheet pile dewatering well structure

Abstract

The invention provides a steel plate pile precipitation well structure. The steel plate pile precipitation well structure comprises steel plate piles respectively formed with two hook-holding portions on two opposite sides, H-shaped steel beams transversely supported on the inner sides of the steel plate piles in the splicing direction of the steel plate piles, and supporting steel pipes connected among the H-steel beams to uniformly support the H-steel beams, wherein the steel plate piles are continuously and vertically arranged in a foundation pit through the hook-holding portions in a spliced mode. Therefore, the problems of higher cost, easy collapse, poor precipitation effect and the like of a traditional precipitation well are solved and the purposes of considering the low construction cost of the traditional precipitation well and efficient precipitation are achieved by arranging the continuously spliced steel plate piles adjustable in number in the foundation pit and arranging the H-steel beams and the supporting steel pipes on the inner sides of the steel plate piles.

Description

technical field [0001] The invention relates to the technical field of water wells, in particular to a dewatering well structure. Background technique [0002] The precipitation well is a well drilled for lowering the groundwater level. After drilling, the water pump is put into the groundwater to reduce the groundwater level. It is one of the measures to ensure the smooth construction of the foundation pit. Traditional precipitation wells are mostly tube well structures. [0003] However, traditional tube wells are only suitable for installation in non-rock formations. Not only do they have high requirements for the construction environment, but the overall structural strength is also poor, and they are prone to collapse. Moreover, the diameter of the tube well is small. In order to meet the design dewatering requirements, generally The efficiency of precipitation can only be improved by building multiple precipitation wells. Therefore, traditional precipitation wells nee...
